The Dopping Adhesive that we offer is Loctite 404 (a “CA super glue” selected from a range of others). Fast-acting and reliable – ready to facet 5 minutes after application (give it a tug to confirm adhesion). Often used in conjunction with a formed wax. A drop will accomplish the adhesion task. Caution: CA adhesives can stick to your skin – so, careful with your fingers. The 3 oz bottle has a one-year shelf-life, kept in refrigeration – there are many ”drops” in that bottle. Remove the stone from the dop by soaking in acetone or (in transferring) by application of heat to the Dop.
